功能介紹
The Image to Base64 tool converts images into Base64 strings you can embed directly in HTML, CSS, or JSON. It is useful for small icons, inline assets, and quick prototyping.
什麼時候用這個工具？
Use this tool whenever you want to inline an image: embedding icons in stylesheets, packaging assets in JSON, or testing image‑related APIs.
使用步驟
1
Upload an image
Drag and drop an image or use the upload button to select a file from your device.
2
Convert to Base64
The tool generates a Base64 string representation of the image entirely in your browser.
3
Copy the encoded string
Copy the Base64 output into your HTML, CSS, or configuration file as needed.
使用範例
Embedding a small icon in CSS
Convert a PNG icon to Base64 and use it as a `background-image` data URI to avoid extra HTTP requests.
